Chuno blurs out Lee Da Hae's revealing scene

Lee Da Hae's revealing scene where she showed some skin was censored with a mosaic effect on the drama Chuno. People are upset that they blurred out the scene. Her character got hurt and when she was receiving treatment from Oh Ji Ho's character, he had to take off the top layer of her traditional Korean outfit. Lee Da Hae's skin was blurred out completely, though she wasn't revealing much. Viewers are saying that it would've been fine if they showed it without the mosaic effect. They're also saying it was unnecessary and the staff of the drama was listening too much to viewers who didn't want the show to get too inappropriate. This whole controversy doesn't seem to be too much of a problem though, because the viewership rating for this episode was a whopping 34%. But anyway, since when is cleavage inappropriate?
